Let 𝐻 be a Hilbert space and 𝐶 a nonempty closed convex subset of 𝐻 . Let 𝐴 𝐶 𝐻 be a maximal monotone mapping and 𝑓 𝐶 𝐶 a bounded demicontinuous strong pseudocontraction. Let { 𝑥 𝑡 } be the unique solution to the equation 𝑓 ( 𝑥 ) = 𝑥 + 𝑡 𝐴 𝑥 . Then { 𝑥 𝑡 } is bounded if and only if { 𝑥 𝑡 } converges strongly to a zero point of A as 𝑡 which is the unique solution in 𝐴 1 ( 0 ) , where 𝐴 1 ( 0 ) denotes the zero set of 𝐴 , to the following variational inequality 𝑓 ( 𝑝 ) 𝑝 , 𝑦 𝑝 0 , for all 𝑦 𝐴 1 ( 0 ) .
